如何從PHP Laravel中的自定義類型的Json文件讀取數據？

Question

這是我的Json文件內容，我想刪除括號和方括號，僅打印數字：

{"prices":[
[1367107200000,135.3],[1367193600000,141.96],[1367280000000,135.3],[1367366400000,117.0],[1367452800000,103.43],[1367539200000,91.01],[1367625600000,111.25],[1367712000000,116.79],[1367798400000,118.33],[1367884800000,106.4],[1367971200000,112.64],[1368057600000,113.0],[1368144000000,118.78],[1368230400000,113.01],[1368316800000,114.713],[1368403200000,117.18],[1368489600000,114.5],[1368576000000,114.156],[1368662400000,115.5],[1368748800000,123.1],[1368835200000,123.88],[1368921600000,120.501],[1369008000000,122.58],[1369094400000,122.9],[1369180800000,123.0],[1369267200000,125.748],[1369353600000,131.7],[1369440000000,130.77],[1369526400000,134.6],[1369612800000,128.985],[1369699200000,129.179],[1369785600000,132.13]
]}

我喜歡這樣：

$str = file_get_contents('Myfile Link Address');
$json = json_decode($str,true);

print_r($json['prices']);

結果是這樣的：

Array
(
    [0] => Array
        (
            [0] => 1367107200000
            [1] => 135.3
        )

    [1] => Array
        (
            [0] => 1367193600000
            [1] => 141.96
        )

    [2] => Array
        (
            [0] => 1367280000000
            [1] => 135.3
        )
)

我希望結果是這樣的：

[1367107200000,135.3],
[1367193600000,141.96],
[1367280000000,135.3],
[1367366400000,117.0]
...

我該怎么辦？

Answer 1

foreach($json["prices"] as $key => $value)
{
    echo "[".$value[0].",".$value[1]."],";
}
